Is LM an interaction?
The IS-LM model describes how aggregate markets for real goods and financial markets interact to balance the rate of interest and total output in the macroeconomy. IS-LM stands for “investment savings-liquidity preference-money supply.”

Is-LM a limitation?
The IS-LM model, however, suffers from two serious limitations: (a) It is a comparative-static equilibrium model. It ignores the time-lags which are important in examining the effects of economic policy changes. (b) If has been called the fix-price model.
How to interpret interaction coefficient in are part 1 lm?
So this post is divided in three parts: i) interaction between two categorical variables, ii) interaction between one continuous and one categorical variables and finally iii) interaction between two continuous variables.

Why are the results of LM and interaction different?
The results are different because the way lm sets up the model with the interaction is different from how it is set up when you set it up yourself. If you look at the residual sd, it’s the same, which indicates (not definitively) that the underlying models are the same, just expressed (to the lm internals) differently.
How to include interaction in regression using are programming?
Then, If X1 and X2 interact, this means that the effect of X1 on Y depends on the value of X2 and vice versa then where is the interaction between features of the dataset. Now that we know that if our dataset contains interaction or not. We should also know when to take interaction into account in our model for better precision or accuracy.
How to plot the marginal effect of an interaction?
To plot marginal effects of interaction terms, at least two model terms need to be specified (the terms that define the interaction) in the terms-argument, for which the effects are computed. To plot marginal effects for three-way-interactions, all three terms need to be specified in terms.
